There is very little information on the Deep dungeon as it is now, so I could not find any answer for my problem. I have just completed level 11-20, and my weapon has +6 and armor +4. It tells me that I can't enter the dungeon because the stats are too low. What do I do now? Is there any way to get them up? Or to at least do level 11-20 again so I don't have to start all over? The npc where you can go in the dungeon tells me I can only level my armor inside of the Dungeon, but how do I do it there? Is it all random from some chests and I just have to do it until the stats are somehow high enough?
